不同类型冲击电流对ZnO压敏电阻老化的影响研究

Gaoya dianqi
为了比较不同类型冲击电流对氧化锌（ZnO）压敏电阻直流老化的影响，将相同类型的ZnO压敏电阻样品分别开展2 ms方波（峰值为2 kA）耐受试验和4/10 μs冲击电流（峰值为100 kA）试验。实验结果表明，在1~3轮（3~9次）的冲击耐受下，2 ms方波对ZnO压敏电阻的老化特性能起到一定优化作用，而4/10 μs大电流冲击则使得ZnO压敏电阻老化特性持续劣化。利用扫描电子显微镜（SEM）、光谱仪、数字源表研究其微观结构以及电气性能参数变化。结合实验结果分析原因，4/10 ...

高空电磁脉冲作用下氧化锌压敏电阻性能研究

Dianci bileiqi
高空电磁脉冲具有场强幅值高、影响范围广、频谱范围宽等特点，能够通过场线耦合在电力系统形成高压、大电流脉冲，从而造成电力系统设备绝缘损坏。氧化锌压敏电阻作为电力系统常规过电压保护元件，其防电磁脉冲的钳压泄流性能较为优异。针对高空电磁脉冲作用下氧化锌残压电阻性能问题，搭建高空电磁脉冲试验效应冲击平台，对高空电磁脉冲作用下氧化锌压敏电阻过冲峰值、残压和响应时间特性进行研究。结果表明：在高空电磁脉冲效应试验上升沿20ns、半高宽500ns的波形冲击下 ...
